| description | The invention discloses a CO detection module applied to fire-fighting safety. The CO detection module comprises a CO sensor U1, a resistor R1, a capacitor C1, a field effect transistor VS, an operation amplifier U3, and an operation amplifier U2, a pin C of the CO sensor U1 is connected with the capacitor C1 and an output terminal of the operation amplifier U3, a pin R of the CO sensor U1 is connected with a D electrode of the field effect transistor VS and a resistor R5, the other terminal of the resistor R5 is connected with the other terminal of the capacitor C1 and a resistor R6, the other terminal of the resistor R6 is connected with an inverting terminal of the operation amplifier U3, a non-inverting terminal of the operation amplifier U3 is connected with a grounding resistor R7, an S electrode of the field effect transistor VS is connected with a pin W of the CO sensor U1 and a resistor R4, and a G electrode of the field effect transistor VS is connected with a power supply VCC via a resistor R3. According to the CO detection module applied to the fire-fighting safety, signals detected by the CO sensor can be processed and sent to a controller, the circuit structure is simple, the cost is low, the size is small, the service lifetime of the alarm controller can be greatly extended by employing the module, and the stability is improved. |
